Homework Statement
Tan(15deg)/(1-Tan^2(15deg)
In my solution manual this is what they did...
2/2 * Tan(15deg)/(1-Tan^2(15deg)
= 1/2Tan(30deg)
Ok first off... I noticed they multiplyed by a fraction of one (2/2) which resulted in
2*tan(15) in the numerator... ( I did not know that you could multiply the coefficient infront by the deg in parenthesis to get tan(30)??)
Second: Where did the denominator go?
